[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 In this embodiment of the present invention, a detachable lithium battery assembly frame includes a combined frame assembly 1 for providing fixation for multiple lithium batteries 2. The combined frame assembly 1 is composed of a base plate unit 1a, an end plate unit 1b, a side plate unit 1c, and an upper pressing member 1d. The base plate unit 1a, the end plate unit 1b, and the side plate unit 1c form a rectangular frame structure for placing the lithium batteries 2. The upper pressing member 1d is used to press the top of the lithium batteries 2 placed inside the rectangular frame structure.

[0030] The base plate unit 1a, end plate unit 1b, side plate unit 1c, and upper pressure component 1d are detachable from each other, which enables convenient disassembly of the lithium battery 2.

[0031] The base plate unit 1a includes a base plate 101, a horizontal slide groove 102, and an end face insertion groove 103; the end plate unit 1b includes an end face pressure plate 105, a fixing block 106, and a limiting block 107.

[0032] The horizontal slide 102 and the end face insertion groove 103 are symmetrically opened at both ends of the top of the base plate 101 and completely penetrate the bottom of the base plate 101. The end face insertion groove 103 is distributed in the middle of the horizontal slide 102 and is perpendicular to the horizontal slide 102. The horizontal slide 102 and the end face insertion groove 103 are in the shape of a cross.

[0033] The fixing block 106 is fixed to the bottom of the end face pressure plate 105, and the limiting block 107 is fixed to the bottom of the fixing block 106. The fixing block 106 and the limiting block 107 are in an "L" shape.

[0034] The limiting block 107 passes through the end face insertion groove 103 from top to bottom and then rotates 90 degrees so that the end face pressure plate 105 is attached to the upper surface of the base plate 101 and is perpendicular to the base plate 101, which is used to realize the assembly of the end face pressure plate 105 and the base plate 101.

[0035] Side panel unit 1c includes a side connecting plate 109 and an L-shaped hook block 110;

[0036] The top two sides of the base plate 101 are symmetrically provided with side insertion grooves 104, which penetrate through the bottom of the base plate 101.

[0037] The L-shaped hook block 110 is fixed to the bottom of the side connecting plate 109. The side connecting plate 109 passes through the side insertion groove 104 through the downward-facing folded part of the L-shaped hook block 110 and is rotated ninety degrees so that the side connecting plate 109 is upright and perpendicular to the upper surface of the base plate 101, which is used to realize the assembly of the side connecting plate 109 and the base plate 101.

[0038] The side flange and top flange of the end face pressure plate 105 are provided with mounting holes for connecting the side connecting plate 109 and the upper pressure member 1d, and the side connecting plate 109 and the upper pressure member 1d are provided with corresponding connection holes.

[0039] In this embodiment: the operation steps of this combined frame component 1 are as follows;

[0040] First, assemble one end plate unit 1b with the base plate unit 1a: adjust the end face pressure plate 105 to a horizontal position, and align the vertically distributed limiting blocks 107 with the end face insertion slots 103 and insert them downwards. Finally, the limiting blocks 107 completely penetrate the end face insertion slots 103. At this point, rotate the end face pressure plate 105 upwards by ninety degrees so that it is perpendicular to the upper surface of the base plate 101. In this way, the limiting blocks 107 are horizontal and fit against the lower surface of the base plate 101, thus completing the assembly of the end face pressure plate 105 and the base plate 101. Then, assemble the other end plate unit. 1b is assembled with base plate unit 1a (it should be noted that when assembling end plate unit 1b with base plate unit 1a, base plate 101 is placed on its side, that is, the bottom of base plate 101 does not contact the worktable, so as to provide space for the flipping of limit block 107. At the same time, after the two end plate units 1b are installed, the base plate 101 is flipped and placed horizontally on the worktable, and the two end plate units 1b are slid away from each other to the farthest end of the two horizontal slide grooves 102, so that the distance between the two end plate units 1b is greater than the arrangement length of the multiple lithium batteries 2 to be assembled).

[0041] Then, multiple lithium batteries 2 can be arranged sequentially on the upper surface of the base plate 101 (it should be noted that adjacent lithium batteries 2 are separated by epoxy boards).

[0042] After the lithium batteries 2 are arranged, the side plate unit 1c and the bottom plate unit 1a are assembled: the side connecting plate 109 is tilted, and the folded edge of the L-shaped hook block 110 facing downward is aligned with the side insertion groove 104 and inserted. At the same time, the side connecting plate 109 is flipped to approach the lithium battery 2. Finally, the side insertion groove 104 is perpendicular to the bottom plate 101 and fits against the side of the lithium battery 2. The L-shaped hook block 110 passes through the side insertion groove 104 and forms a hook with the lower surface of the bottom plate 101.

[0043] Then, using external tools (e.g., pneumatic push rods), the two end face pressure plates 105 are pressed towards the middle simultaneously, so that the two end face pressure plates 105 approach the arranged lithium batteries 2 and press them together. Finally, the mounting holes on the end face pressure plates 105 are aligned with the connecting holes on the side connecting plate 109. At this time, by screwing through the connecting holes and threadedly connecting them to the mounting holes, the side connecting plate 109 and the end face pressure plates 105 can be fixed, and at the same time, the horizontal positioning and fixing of the lithium batteries 2 is completed.

[0044] Finally, the upper pressure piece 1d is placed on the end face pressure plate 105 and the top of the lithium battery 2, and screws are threaded through the connecting holes on the upper pressure piece 1d and the mounting holes on the top folded edge of the end face pressure plate 105 to achieve the connection and fixation of the upper pressure piece 1d and the end face pressure plate 105, and at the same time, the lithium battery 2 is vertically fixed.

[0045] By combining the above components, multiple lithium batteries 2 can be easily assembled and fixed. At the same time, when it is necessary to disassemble and repair the lithium battery 2, simply reverse the above steps to easily remove the upper pressure component 1d, the side plate unit 1c, and the end plate unit 1a. This allows for convenient disassembly and separation of the lithium battery 2.

[0046] Please refer to this carefully. Figures 1-4 The end face pressure plate 105 has a notch 108 near the bottom of its end face, which provides space for the end face pressure plate 105 to flip.

[0047] In this embodiment, the notch 108 provides space for the limiting block 107 to pass through the end face insertion slot 103, ensuring smooth installation of the end face pressure plate 105.

[0048] Please refer to this carefully. Figures 1-5The width of the limiting block 107 is greater than the width of the fixing block 106 and matches the width of the end face insertion groove 103. The length of the limiting block 107 in the horizontal state is greater than the length of the end face insertion groove 103.

[0049] The width of the side insertion slot 104 is greater than the width of the two folded edges of the L-shaped hook block 110;

[0050] The bottom of the base plate 101 has concave grooves formed at the corresponding positions of the horizontal sliding groove 102, the end face insertion groove 103, and the side insertion groove 104.

[0051] In this embodiment: by having a horizontal limit block 107 with a length greater than the end face insertion groove 103, the horizontal limit block 107 can not pass through the end face insertion groove 103, thus ensuring a stable connection between the end face pressure plate 105 and the base plate 101.

[0052] The structure in which the width of the side insertion slot 104 is greater than the width of the two folded edges of the L-shaped hook block 110 provides space for the flipping of the L-shaped hook block 110.

[0053] The concave groove structure prevents the limiting block 107 and the L-shaped hook block 110 from protruding from the lower surface of the base plate 101, thus enabling the combined frame assembly 1 to be placed stably.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
